Best choice!
Color: Charcoal Gray, Size: 66" Wide x 70" Tall Without Window
This workstation partition really was a good choice. It took me a bit of time to decide - I was looking for something reliable, noise absorbing, and professional-looking while also being space saving instead of the clunky typical cubicle walls. This was perfect! It successfully created 2 cubicle type units in a room that was anticipated to only be enough room for one cubicle. I am happy with it!

NO DELIVERY DO THEY EVEN HAVE THE PRODUCT TO SELL??
Size: 5 Panels, Color: Grey
There is a problem with the Seller delivering on the products sold. Or someone is selling on behalf of the seller and not being able to deliver. Purchased 3-part panels used no problem, and are nice, but we also needed the 5-panel divider. which has been promised twice for delivery and NOT delivered without explanation. We'll have to send the other back as we'll need something that match.
